noward lrAi-nolikochland, Applicatlon october 9,1836, Serial No.-: 1l4,911 1 Claim. (01. 14-2318) This inventionrelatesto a pulley-likestructure such as is used 1forieed wheels or tension wheels, andparticularly tofeed wheels or tension wheels of the type 'in'which theperipheral 15 groove for receiving the strand, cord orthe like is formedby two series of radially-extending with the arms ononeside of thegroove having a staggeredrelation-tothe arms on the other side of thegroove.

Q .10 Oneof the objects of the invention is to provide a novel feedwheel of this type which is simple in construction and which can beinexpensively manufactured and also to provide-a feed wheel having a rimoneach side of the groove 15 integral with the arms.

' My improved feed wheel or tensionwheel is made from two similardisk-like members of sheet material, each having a central body portionand a plurality of arms extending outwardly from the body portion inradial directions and a rim portion connecting the ends of the arms, the

body portion, arms and rim portion of each memher being integral witheach other. The two members are assembled with the body portions thereofin registering engagement, and the arms ofeach member are so shaped thata portion of each arm of each disklike member enters a space between twoadjacent arms of the other disk-like member so that the arms of the twodisk-like members have a crossing relation. The outer ends of the armsof each member flare outwardly and. the rimportions of each member alsoflare outwardly, whereby the pulley is provided with a peripheral vgroove with interrupted side walls, each side wall having openingsopposite the solid portions of the other wall.

In the drawing wherein I have shown a selected embodiment of theinvention;

Fig. 1 is a view of one of the disk-like" feed 40 wheel members; 1

Fig. 2 is a view of the other feed wheel member' sembled to make thecomplete feed wheel; 45 Fig. 4 is a section on the line M, Fig. 3.

My improved feed wheel comprises the two similar members I and '2. eachof which is stamped'out from sheet"- material, preferably sheet metal.Each member comprises a central portion 3 havinga plurality ofarms 4radiating therefrom, and a narrow, continuous rim section, 5 integralwith thearms and connecting the outer ends thereof. Each arm 4 of eachmember is deformed by'being bent laterally as indicated 55 at 6, therebyforming. ashorter arm section I4 some a sinuous course whereby there isprovided an excellent gripping or frictional engagement between thewheel and the cord. The narrow 1 1g. 3 is a side view of the two membersas-'.

which connects to the central portion 8 and inciines in onedirectionrelative to the plane thereof and a longer arm. section IImaking an angle with the shorter-arm section I4 and which inclines intheopposlt'e direction relative to the plane'of the central: portion.'Theiarms of each member are spaced from each'other: by a distance'slightly greater. "than the width of the arms of the other member andthe two members I and 2 are assembled' wlth the central portions 3 ofthe two members' inregistering relation, as shown in Fig.4, and-with theofiset portion I of each arm of one member occupying the spaces 1between the arms ofj the other member, as best seen in Fig. 4. ,Withthis arrangement the arms of the two members haves. double crossingrela- Gil tion, the shorter arm sections ll of one member crossing thoseof the other member and the longer arm sections" of each member likewisecrossing those of'the other member- This crossing relationof the longerarm sections I! forms a V groove 8 having interruptedside walls, eachside wall having openings formed by the spaces I in the -disk=likemembers and the openings in eachside wall being opposite the solidportions of the other sidewall formed by the arms 4. 'The V groove thusprovided has the solid portions of its two walls in staggeredrelation sothat when a cord or'strand is laid in the groove it will ascontinuousrim sections"! have the advantage that they facilitate the feeding orlaying ofi the cord in the groove. v

The two members I and 2 may be secured together'in their assembledrelation in any suitable way. Asherein shown thesemembers are mounted ona hub I0 which is adapted to be securedto a shaftor other-support. Thishub is shown as having one end II reduced in diameter and the. centralportions 3 of the members I and 2 are provided with a central opening I!of a size V to fit" over the hub portion II of reduced diamtherebylocklng'the'two wheel members in place.

These wheel members, however, might be spotweldedtogether or securedtogether in any de- The complete feed wheel is thus made up of twosimilar sectionswhich when assembled prov vide a V groove having-smoothedges, but with thev arms I of the two members having a staggeredcrossing'relation which, as stated-above, B5

10 feeding it forward. 1

A wheel embodying-my invention is also well suited for use as a tensionwheel.

I claim:

A feed wheel comprising two similar disk-11k 5 members of sheetmaterial, each having a central portion, spaced arms extending radiallyfrom the central portion, and a narrow continuous rim portion connectingthe ends of the arms, each arm being bent to present a shorter inner armsection connected to the central portion and in- 011111118 in onedirection relative to the plane thereof and a longer outer arm sectionconnected to the rim portion and which inclines in the oppositedirection relative to the plane of the central portion and thereby makesan angle with the shorter arm section, said disk-like members beingassembled with the central portions in registering engagement and withthe apices of the bent portions of the arms of one member occupying thespaces between the arms of the other member, and with the longer outerarm sections of the two members having a crossing relation and formingbetween them a V groove having interrupted side walls, each side wallhaving openings opposite the solid portions of the opposite side wall.
